BROODER.

Application filed October 16, 1925. Serial No. 62,882. r

This' invention relates to improvements in brooders for use in hatcheries in the brooding of baby chicks and contemplates the provision of a brooder using an incandescent lamp bulb as its medium of heat so enclosed as to eliminate any possibility of the baby chicks coming in direct contact with the incandescent lamp bulb. I

Another object of my invention resides in the construction of the breeder per se constituting a base portion having a sleeve or enclosure provided upon its upper side for reception within a tubular member forming.

the enclosure with the incandescent lamp bulb while a canopy is arranged and sup ported in spaced relation upon the upper end of the tubular member in order that ample and suficient space may be defined therebetween to allow the heat thus thrown from the incandescent lamp bulb to travel upwardly within the tubular member and be deflected against the inner side of the canopy, so supported, in order that the baby chicks so surrounding the base portion of the brooder will have the heat deflected and focused directly upon their backs.

With the above and other objects in view, the invention further includes the following novel features and details of construction, to be hereinafter more fully described, illustrated in the accompanying drawing and pointed out in the appended claims.

In the drawing Figure 1 is a vertical sectional View of my invention.

Figure 2 is a transverse section taken on the line 22 of Figure 1.

Referring to the drawing in detail, wherein like characters of reference denote corresponding parts, the reference character 10 indicates a substantially inverted cup-shaped member which forms a base or support. A reduced sleeve 11 extends centrally and vertically upon the upper side of the base for reception within a tubular member 12 having a plurality of arms 13 arranged at spaced intervals upon the periphery thereof. A substantially inverted conical shaped canopy 14 is supported on said arms 13 in spaced relation with respect to the upper periphery of said member 12. A plurality of companion spring fingers 15 are secured as at 16 to the upper side of the base 10 within 'member 12 and sleeve 11.

the sleeve 11, the purpose of which will be,

presently apparent. I

In order to provide means for creating suitable radiation and heating medium for the brooder, as completed, an incandescent lamp bulb 17 is'inserted within the tubular Said bulb is thus held against accidental displacement and in spaced relation with respect to the inner side walls of the tubular member 11 between the companion spring lingers 15. Conducting wires 18 leading from the socket 19 therefor are guided through a dielectric bushing 20 provided in the apex of the conical shaped canopy 14:.

It is manifest that owing to the novel construction of the brooder as described and illustrated, baby chicks after hatching will be kept warm and free from any injury or ill effects from the brooder in so far as the chicks may not come in direct contact with the heating medium, namely the incandescent lamp bulb 17. The heat radiated by the lamp bulb passes upwardly through the tubular member 12 and is deflecteddownwardly upon their backs from the inner sides of the conical-shaped canopy l l. Obviously a rheostat or like instrument may be utilized in regulating the heat to be thrown, generated 0 1: radiated by the incandescent lamp bulb 1(.

The invention is susceptible of various changes in its form, proportions and minor details of construction, and the right is herein reserved to make such changes as properly fall within the scope of the appended claims. I

Having described my invention, what I claim is 1. A brooder of the character" described I comprising a supporting base, a sleeve provided upon the upper side thereof, a tubular member telescopically associated with the sleeve, means for retaining an incandescent lamp bulb within the sleeve and tubular member, and a canopy supported in slight spaced relation upon the upper periphery of the tubular member for deflecting the heat rays generated by the incandescent lamp bulb and emitted from the sleeve and tubular member around the supporting base.

2. A brooder of the character described comprising a supporting base having a sleeve extending Vertically and centrally upon the upper side thereof, a plurality of companion spring fingers supported upon the upper side of the supporting base Within the sleeve, a tubular member telescopically associated With the sleeve to provide a support and enclosure for an incandescent lamp bulb positioned therein, and a substantially inverted conicalshaped canopy arranged in slight spaced relation with respect to the upper periphery of 10 the tubular member deflecting the heat rays from the sleeve and tubular members around the supporting base.

In testimony whereof I aiiix my signature.
